I was able to install some high density foam in the form of two different sheets, side by side, using the video provided by the user who started this thread.
I picked up two of what appears to be the same gardening knee pad that you show in your photo for comparison purposes, at the local Rite Aid, for $2 each. The brand is Bloom and the size is about 7-1/4" by 14". They are exactly the right size to slip under the seat cushion, one on either side of the seat heating wire, with no cutting required.
I did this modification today. It cost $4, took about 10 minutes, required no tools, and is completely reversible, It completely fixes the uncomfortable seat problem.
